The Loudness War
The music industry's tendency to record, produce, and broadcast music at progressively increasing levels of loudness to create a distinct sound is known as the Loudness War. Because the maximum amplitude of recorded music cannot be increased, overall loudness can only be boosted by reducing the dynamic range of source audio and distorting recordings, leading to complaints from some audiophiles.
In 1997, Iggy Pop assisted in the remix and remaster of the 1973 album Raw Power by his former band The Stooges, arguably creating the loudest rock CD ever, reaching −4 dBFS in places.
